ANIIv'IAL-SHEARS.

SPGIFICATION forming part of Letters Patent No. 678,161, dated July 9, 1901.

Application filed April 17, 1900.' Serial No. 13,179. (Nomodel.)

To all when?, t may concern:

Be it known that I, BAINBRIDGE rPERCY CLARK, a citizen of the United States, and a resident of Choteau, in the county of Teton and State of Montana, have invented certain new and useful Improvements in Animal- Shears, of which the followingis a full, clear, and exact description. r

My invention relates to an improvement in animal-shears, and comprises certain novel.

features and combinations of parts, which will be hereinafter particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the' figures.

Figure l is a sectional plan of my device, the section being taken just beneath the cap. Fig. 2 is a vertical section of the same, and Fig. 3 is a vertical section of the vibrating lever removed from the other parts.

In the present specification and drawings my device is described and shown in the manner now preferred by me, although it will be evident that the device may be varied from the construction herein shown Without departing from the spirit of my invention.

The following is a description of the device as shown in the accompanying drawings:

The operating mechanism is inclosed witha in a casing formed by the main or casing member A, which is open at the top and closed when in use by means of a cap C. Within the chamber thus formed are placed the vibrating lever B and its operating mechanism, and at one end of the casing said lever projects and has the cutter F secured thereto and cooperating with the comb E, which is secured tothe casing A. This comb is clearly shown in Fig. 1, and consists of a number of fingers, which have their upper side edges sharpened to form one-half of the cutting device. The lcutter F is herein shown as having three fingers or teeth, which are moved in close contact with the upper surface of the comb and are sharpened, so as to cut hair or wool, which cuts between the fingers of the comb. A combined pivot and tension bolt G passes through the cap C and the vibrating lever and is screwed into the bottom of the easing A, as clearly shown in Fig. 2. The

cap is secured in place upon the casing by means of said bolt, which presses thereon through a spring H, which surrounds the bolt and engages the bolt-head and top of the vibrating lever. The vibrating lever B is pivoted upon the bolt G and is also held down, so as to hold the cutter and comb in close contact, by means of pressure applied through the medium of said bolt. This pressure is applied to the vibrating lever by means of an arm, which is provided with a sleeve or collar closely surrounding said bolt and connected Vwith the lever at a point near the cutter F or any convenient point between the pivot and said cutter F. This arm and collar may be made entirely independent of the vibrating lever B or, as herein shown, as a part of said lever. 'Thislevera as herein shown, is pro-v vided with two longitudinal slits arranged at each side of its center line and dividing this portion of the lever into a central arm b and two outer arms b. The central arm b' carries the collar or sleeve b2, which closely ts about the combined pivot and tension bolt G. As herein shown, the outer arms b extend about the collar b2 to the rear end, being thus held out of direct contact with the pivot-bolt G.

With this construction the pivotal support of the vibrating lever is through the arm b. It is very evident,however,that the vibrating lever B may .be directly pivoted upon the bolt G and the arm b and collar b2 be made as a separate member,which is either fixedly secured to the vibrating lever B or has its outer end bearingupon the top of the lever B. The object of this particular construe tion is to transfer the pressure upon said collar b2 through the arm e to a point upon the vibrating lever nearer the cutter than if the pressure were applied directly tothe .lever at its'pivot-point. As the collar b2 snugly ts upon the pivot-bolt,pressure applied thereto lengthwise of the bolt will be transferred through the arm b/ to the vibrating lever B at the point where thetwo unite. By this means the pressure is applied nearer the cut= ter, and as a consequence thereof .the device willwork more satisfactorily than if the pressure were applied directly at the pivot-point.

The cap C is herein shown as provided with a recess or socket C', surrounding the outer' portion of the pivotbolt,and contains a coiled spring I-I, which bears upon the lower portion of said socket and upon the under surface G of said bolt. The upper end surface of the collar b2 engages With the lower surface of the cap,and the pressure is transferred from the bolt to said collar b2 through the spring II and cap C. The lever B is vibrated by any usual mechanism. The mechanism herein shown consists of a rotating shaft D, which is journaled in the handle I and is provided at one end With a crank-disk D and a crankpin D2, the latterlyingwithin a slot b4, formed in an upturned portion of the lever B at its rear or inner end.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In animal-shears the combination of, a combined pivotand tension bolt anda vibrating lever pivoted thereon, and having an arm extending from the point removed from its pivot and provided with a sleeve or collar closely surrounding the pivot-bolt,and means for applying pressure to said collar, substantially as described.

2. In animalshears the combination with the cutters, anda pivot-bolt, of` a vibrating lever carrying one ot' said cutters, an armex-h tending from the cutter-engaging-end of said leverand having a collar or sleeveittingabout the pivot-bolt, and means for applying pres: sure to said collar or sleeve in thedirection of its axis, substantially as described.

3. In animal-shears, the combination with the cutters, a vibrating lever carrying one of said cutters, a pivot-bolt therefor, an` arm4 having a collar or sleeve thereon surrounding said pivot-bolt and its outer end engaging the cutter-carrying end ot' the vibrating le thereby to apply pressure upon the vibrating lever, and means for regulating the tension -of said spring, substantially as described.

5. Animal-shears, comprising a casing hav- :ng a. comb secured thereto, a vibrating 1e- ,ver, a detachable cutter carried by said le- 1ver, a combined tension and pivot bolt screwing into the casing, an arm having a collar or sleeve at one end surrounding said bolt and lits other end engaging the vibrating lever to hold the cutter down, a casing-cap beneath the head ot' the said bolt and engaging the sleeve upon said arm, and a spring between the holt-head and said cap, substantially as described.

In` testimony whereof I have signed my name to this specification in the presence of the two.subscribing'Witnesses.
